b all whom it may concern:

Be it known that I, CLAIBORNE C. Pmrnn, a citizen of the United States, and a resident of Denison, in the county of Grayson and State of Texas, have invented certain new and useful Improvements in Heaters,

of which the following is a specification.

My invention is an improvement in heaters, and has for its object to provide a heater especially adapted for use with internal combustion engines, for the preliminary heating of the manifold before starting, to assist in starting in cold weather.

In the drawings:

Figure 1 is a front view of the improved heater in place;

Figs. 2 and 3 are sections on the lines 2 2 and 3-3, respectively, of Fig. 1, each view looking in the direction of the arrows adj acent to the line;

Fig. 4: is a section at right angles to Figs. 2 and 3; V

Figs. 5, 6 and 7 are sections on the lines 55, 66 and 7-7, respectively,of Fig. 4, each view looking in the direction of the arrows adjacent to the line.

The present embodiment of the invention is shown in connection with the manifold 1 p of an internal combustion engine, the heater being arranged at the connection 2 between the manifold and the carburetor (not shown). The heater comprises a casing 3 of substantially rectangular cross section, and having an opening in one wall and its ends for receiving the connection 2, the edges of the walls of the heater casing 1 fitting closely about the connection to form a tight joint at the said connection.

Transversely of this heater casing near the bottom and near the front or outer wall there is provided an auxiliary casing or firebox 4, the said casing or firebox 4 being adapted to contain a wick 5 of asbestos or the like.

extends longitudinally of the auxiliary casing and transversely of the main casing 3, the bolt passing through registering openings in the casings and being engaged by a nut 8 at one end to hold the parts in place.

In order to permit the insertion of gasolene or other fuel in the auxiliary casing, an

opening9 is provided at one end of the main.

casing just above the trough of the auxil-r iary casing, for the insertion of a spout, nozzle orthe like, and this opening is adapted to be closedby a swinging door 10 which has a fingerpiecefor manipulating the same as shown in Figs. 1 and 2.

The casing 3 is PIOVlClGClnear its bottom in its front wall with a series of air inlet" openings 11 and in its top near the rear wall the casing is provided with a series of air outletopenings 12, the said openings being arranged on each side of the connection 2. The casing is also provided with a series of inlet openings 13 in each side, the said series being arranged in inclined relation as shown, and swinging 1 doors. 14 are provided for closing the openings,a door being arranged at each side ofthe main casing. Another air inlet 15 is provided just, above the series 11, and a swinging door 16is arranged between. the inlet 15 and the series 11, the said door being arranged to close either the inlet 15 or the series 11.

The casing 3 is secured to the manifold 1 by means of a clamp composed of L-shaped sections 17 Each of these sections comprises a portion lapping alongside the heater casing and a portion extending upwardly and embracing the manifold. A bolt 18 is passed through the registering openings in the ends of the vertical portions, and is engaged by a nut-19 to clamp the said portions on to the manifold. A second bolt 20 is passed through the front end of the horizontal portions of the clamp section, at the front of the heater casing, and this bolt is engaged by a nut 21.

It will be understood that, if desired, the heater may be formed integral with the manifold. The form shown is especially adapted for application to existing engines, since it may be clamped to the manifold. A baflie plate 22 is arranged above the auxiliary casing 4., this baflie plate extending from the front wall of the main casing to near the rear wall, and the said plate has a series of openings, as shown.

In operation, the shutter or swinging door 10 is opened, and from a half to an ounce of gasolene or other liquid fuel is poured into the trough formed by the extension 6 of the auxiliary casing. The fuel is poured in slowly, in order that it may be absorbed by the wick, and'after it has been absorbed the fuel is lighted. When burning, the fuel inlet opening is closed and the draft opens ings are partially closed or left Wide open, according to conditions. As soon the fuel is burning properly, the hood is closed down, and within from two to six minutes the manifold will be at a temperature that will convert the fuel into gas. It will be understood that the difference in the time required to heat the manifold depends upon the weather. When the manifold is hot, the shutters of the draft openings are closed,

' which will at once extinguish the flame.

It will be understood that the attachment shown is especially adapted for existing engines, being capable of attachment to the manifold. It will be obvious that the casing might be cast with the manifold, forming an integral part thereof.

I claim:

1. A device of the character specified, comprising a casing adapted for connection with the manifold of an internal combustion engine, said casing having an auxiliary casing within the same, said auxiliary casing containing a wick of asbestos or the like and having perforations in its walls, air inlet openings in the front and side walls of the casing near the auxiliary casing, shutters for controlling these openings, air outlet openings in the top of the casing, a baffle Copies of this patent may be obtained for five cents each, by addressing the Commissioner plate extending transversely of the casing above the auxiliary casin said baliie plate having openings, the main casing having an opening in one side wall at one end of the auxiliary casing, and a shutter for closing thesaid opening.

A device of the character specified, comprising a casing adapted for connection with the manifold of an internal combustion engine, said casing having an auxiliary easing Within the same, said auxiliary casing containing a wick of asbestos or the like and having perforations in its walls, air inlet openings in the front and side walls of the casing near the auxiliary casing, shutters for controlling these openings, air outlet openings in the top of the casing, and a baffle plate extending transversely of the casing above the auxiliary casing.

3. A device of the character specified comprising a casing, means for securing the casing to the manifold of an internal combustion engine, an auxiliary casing held Within the main casing and having perforated walls and adapted to contain a wick of asbestos or the like, said main casing having inlet and outlet draft openings, means for controlling said openings, and having a fuel inlet opening above the auxiliary casing and at one end thereof, and a shutter for closing the said openings.
